The rule below shows how the cost of an electrical repair depends on the time it takes.

Multiply the hours of labor by $60, then add $45.

If C = cost in dollars and h = hours of labor, which equation expresses the rule above?
here's the answers
A. C(h) = 60(h + 45)
B. C(h) = 45(h + 60)
C. C(h) = 45h + 60
D. C(h) = 60h + 45

Note that the 45 dollars is added  after the cost per hour is calculated.  No matter how many hours are spent on repair the 45 dollars is a constant amount added after the calculation

Well D fits that then perfectly because it has C (h) = 60h + 45 
Thanks so much for your help @cwrw238
